Regulation of synaptic vesicle fusion by protein kinase C

open access: yesThe Journal of Physiology, 1999
Activation of protein kinase C (PKC) by phorbol esters stimulates secretion of neurotransmitters from most presynaptic terminals. This action of PKC may be even more general, because secretion from many non-neuronal cells is also stimulated by these agents.

Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium

open access: yesAdvanced Science, EarlyView.
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.

Differential Release of Exocytosis Marker Dyes Indicates Stimulation-Dependent Regulation of Synaptic Activity

open access: yesFrontiers in Neuroscience, 2019
There is a general consensus that synaptic vesicular release by a full collapse process is the primary machinery of synaptic transmission. However, competing view suggests that synaptic vesicular release operates via a kiss-and-run mechanism.

Fast Snare Mediated Synaptic Vesicle Fusion in Supported Membranes

open access: yesBiophysical Journal, 2013
In vitro reconstitution experiments have played an essential role in a large body of research on SNARE-mediated membrane fusion. One of the open questions is how well reconstituted membranes with recombinant proteins approximate the physiological membrane.Here we report experiments from a hybrid system consisting of purified synaptic vesicles from rat ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Membrane bridging by Munc13-1 is crucial for neurotransmitter release

open access: yeseLife, 2019
Munc13-1 plays a crucial role in neurotransmitter release. We recently proposed that the C-terminal region encompassing the C1, C2B, MUN and C2C domains of Munc13-1 (C1C2BMUNC2C) bridges the synaptic vesicle and plasma membranes through interactions ...

Sustained exocytosis after action potential-like stimulation at low frequencies in mouse chromaffin cells depends on a dynamin-dependent fast endocytotic process [PDF]

open access: yes, 2016
Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable vesicles.
